Looking for schematic diagram for Dell MMS 5650

The unit was accentally plug into a 220V outlet. I already replaced the fuse that was blown out, but the unit doesn't work. So I decided to take servicing the electronic part of the unit, and found out that 2 of the IC's were blown out but the part number was not defined on the casing on the piece so I can not replaced it. I am looking for the schematic diagram and parts for this Dell MMS 5650. Looking forward for a solution.

You will never find a schematic for a dell.

you can purchase this whole unit for the price of those ic's
the going rate is 30 to 70.00
I fix these only if they have frayed wire, otherwise junk pile.
sad but its the times we live in.

Dell mms 5650 to play xbox 360?


You want to hook it up to your xbox or your tv? If it is connected to your tv already just adjust tv/xbox audio settings. If your looking for a place to plug it into your xbox your out of luck. I don't think that can be done without some skilled craftsmanship.

Bose Companion 5 110v/220v short circuit


The fact that everything but the power amp is still working, it could be only a fuse protecting the output that needs replacement although this fuse is probably circuit-wise after the main fuse you have already replaced and could be soldered on the board. Worst case, the output modules are blown and require replacement and depending on the power level it may be worth repairing instead of replacing.
Most modern electronic devices can be set or adapted to line voltages from 100-240 Volts and a good percentage of the devices, using the common switched mode power supply don't need any changes made by the user since they can be inherently 'auto-ranging.'

Replaced fuse but still not working


the speak power system may be burnt out, to check that you need to plug the speakers into a wall outlet and connect the speaker to a boombox (CD player) audio jack out. play some music on the cd player.
if still issue no sound...then check if the power cable of speaker is ok.
take it to a tech

Dell MMS 5650


you will never find a schematic for any dell part.
you can be the first to make one though.

if you know electronics then the circuit for that is one of the easiest.
having a schematic will not help you fix it.

since your looking at an item that sells for 30 to 70.00 any part in there you order will max that.

I find a signal tracer to be invaluable in troubleshooting these.

Similar situation happened with me ... on the back of the subwoofer is a fuse,it's a little round button that actually can come out. Maybe that just popped. try pulling it out and putting it back in.

Usually it "Blows" the primary winding of the step down transformer and often does nothing else, if ya lucky, so try replacing the transformer, sometimes it can also, as well blow the Bridge Rectifier OR rectifier Diodes, on the secondry side. I havent seen schematics have you Goggled for them?
